Title:
THREE-PHASE VIENNA RECTIFICATION CIRCUIT AND DESIGN METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/083123
Kind Code:
A1
Abstract:
Provided are a three-phase Vienna rectification circuit and a design method therefor. The three-phase Vienna rectification circuit comprises a three-phase alternating-current input end, three inductors, three power switch groups, a first capacitor, a second capacitor, a first-type rectifier diode and a second-type rectifier diode. The three inductors are each coupled to the three-phase alternating-current input end. Each inductor comprises a magnetic core and an inductance coil wound round the magnetic core. The three power switch groups are respectively coupled to the three inductors. The first-type rectifier diode is coupled between an output end of a corresponding inductor and an input end of the first capacitor. The second-type rectifier diode is coupled between an output end of a corresponding inductor and an output end of the second capacitor. The end of the inductance coil that is connected to a voltage moving point is arranged in the inner layer of the magnetic core.
